Metabolite Identification
Common NameUndecanoic acid
DescriptionUndecanoic acid, also known as N-undecylic acid or N-undecanoate, belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. Undecanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Undecanoic acid is a potentially toxic compound.

Enzymes

General function:
Involved in catalytic activity
Specific function:
Has medium-chain fatty acid:CoA ligase activity with broad substrate specificity (in vitro). Acts on acids from C(4) to C(11) and on the corresponding 3-hydroxy- and 2,3- or 3,4-unsaturated acids (in vitro). Functions as GTP-dependent lipoate-activating enzyme that generates the substrate for lipoyltransferase (By similarity).
